Magento: Names of the associated products of a configurable product are not visible in admin

The Simple Configurable Products module. In the file
app/code/community/OrganicInternet/SimpleConfigurableProducts/Adminhtml/Block/Catalog/Product/Edit/Tab/Super/Config/Grid.php
the developers of Organic Internet left a nice little hint;

#Copied from Magento v1.3.1 code.#Only need to comment out addFilterByRequiredOptions but there's no#nice way of doing that without cutting and pasting the method into my own#derived class. Boo.#This change stops the filtering-out of any configurable product's 'associated products' that have compulsory custom options#Have also replaced parent::_prepareCollection with Mage_Adminhtml_Block_Widget_Grid::_prepareCollection();

I figured the code that was used in 1.3.1 was outdated so this file
would be outdated if you're using >1.3.1. So I just looked at the
contents of the core file
app/code/core/Mage/Adminhtml/Block/Catalog/Product/Edit/Tab/Super/Config/Grid.php
and looked for differences, and found the culprit.
All you have to do is add this line;
